Mick Schumacher showed solid progress on the second day of IndyCar preseason testing at Sebring International Raceway on Tuesday, February 10, 2026, shaving more than 0.8 seconds off his Monday best as he continues his adaptation to the series ahead of his rookie campaign with Rahal Letterman Lanigan Racing (RLL).

The two-day test wrapped up with the field split into morning (Group 2) and afternoon (Group 1) sessions, reversing Monday’s schedule. Cooler morning conditions favored quicker times, while the afternoon saw temperatures rise to a high of 25 degrees Celsius (77°F), making the track slicker and slower overall.

Marcus Armstrong (Meyer Shank Racing-Honda) topped the combined day with a blistering 52.372-second lap in the morning Group 2 session, edging out the previous day’s benchmark set by defending champion Alex Palou. Sandwiched between Armstrong and Will Power (Andretti Global-Honda, 52.611s) were Kyle Kirkwood (Andretti Global-Honda, 52.479s in Group 1) and Ganassi veteran Scott Dixon (52.514s in Group 2). Scott McLaughlin (Team Penske-Chevrolet) rounded out the top five at 52.636s.

The improvement from his Monday time of around 54.269 seconds (as referenced in team progress reports) demonstrates steady gains in setup understanding and confidence on the challenging 1.8-mile Sebring short course.

The former Formula 1 driver has been methodical in his preparations.

At Sebring, he ran the No. 47 Honda alongside teammates Graham Rahal and Louis Foster, benefiting from their experience. Schumacher’s focus remains on building consistency across the varied 17-race schedule, which includes six ovals. “Schumacher is still fully on track in his preparations for the season,” observers noted, highlighting his positive trajectory despite finishing mid-pack on raw speed.

The test provided valuable data for all teams as the season opener approaches on the Streets of St. Petersburg March 1, followed by Phoenix oval March 7. Armstrong’s pace underscores Meyer Shank’s strength, while Andretti Global (with Kirkwood and Power) and Penske (McLaughlin) showed competitive form. Dixon’s consistent top-three effort reaffirms Chip Ganassi Racing’s threat.

For Schumacher, the incremental gains at Sebring build momentum after his Homestead oval debut, where he described entering corners without braking as “one of the weird parts” but ultimately “fun.” With upcoming open tests at Phoenix February 17-18, the German driver is poised to refine his skills further.

As IndyCar’s 2026 campaign nears, Schumacher’s progress signals potential for the high-profile rookie to surprise in his new environment, blending F1 pedigree with American open-wheel grit.
